Pressure Canner Gauge Testing in Broward County

Canning can be a fun, safe and economical way to preserve food at home.  Canning favorite products to be enjoyed by family and friends can be a pleasant experience and a source of pride and joy for many families and consumers.

Call to Action

Testing your pressure canner gauge regularly is important to ensure proper results.

  • Your pressure canner may have a dial gauge for indicating the pressure and regulating the pressure.
  • Dial gauges should be checked for accuracy before use each year, since older gauges may weaken and become inaccurate.

 

 

Gauges that read high (it says it has more pressure than it really does) cause under-processing and may result in unsafe food. Low readings (it has more pressure than it really does) cause over-processing, and soft, mushy food. Pressure adjustments can be made if the gauge reads incorrectly. Gauges may need to be replaced when readings differ by more than 2 pounds.

 

  1. Handle canner lid gaskets carefully and clean them according to the manufacturer’s directions.
  2. Nicked or dried gaskets will allow steam leaks during the pressurization of canners. Keep gaskets clean between uses.

 

Pressure does not destroy microorganisms, but high temperatures applied for an adequate period of time do kill microorganisms. Adding pressure increases the temperature, which kills bacteria much faster. Clostridium botulinum bacteria are the main reason low-acid foods must be pressure canned to be considered safe. https://nchfp.uga.edu/papers/guide/GUIDE01_HomeCan_rev0715.pdf Home canned foods are responsible for over 90% of all cases of foodborne botulism.
